How to get data about the VK page through a JS script on an external site?

Question

JavaScript

With these magic lines:

<script src="https://vk.com/js/api/xd_connection.js?2" ></script>
<script>window.name='fXD';
VK.init(function() {
// API initialization succeeded
// Your code here
console.log('API is working!\n\n')
}, function() {
// API initialization failed
// Can reload page here
console.log('API is not working...')
}, '5.124');</script>

I successfully connected the API itself to my site, but it's not at all clear how to make a request to get public data about any user by his id.
I tried to call the function with this code, but nothing is output to the console.

VK.api("users.get",{"user_ids": "durov", "fields":"city", "v":"5.89"},function(data){
     console.log(data);
 })

How to get public user data using the VK API and an external site without their authorization on the site? The idea is to put the user ID in input and output data from the returned data array. Is it real at all?

Answer 1

Without authorization, the API cannot be used anywhere. These are basic concepts. Without authorization - only parsing.
Authorization is precisely for this purpose made in order not to allow such cunning people like you to make anonymous requests to api and to be able to disconnect you from the service at any time
